Genetic influences on blood pressure response to the cold pressor test
: Results from the HAPI heart study.
O teste pressorico ao frio (Cold Pressor Test
) geralmente e realizado de forma analoga a originalmente descrita por Hines e Brown, tal como foi publicado no American Heart Journal, em 1936.
Abbreviations: ALLO = allopregnanolone and pregnanolone, ANOVA = analysis of variance, BMI = body mass index, CPT = cold pressor test
, CPX = cardiopulmonary exercise testing, CSF = cerebrospinal fluid, CSU = clinical studies unit, CV = coefficient of variation, DHEA = dehydroepiandrosterone, DHEA(S) = DHEA-sulfate, DSM-IV = Diagnostic and Statistical Manual of Mental Disorders-4th Edition, EKG = electrocardiogram, GABA = gamma-aminobutyric acid, GC-MS = gas chromatography-mass spectrometry, IV = intravenous line, NPY = neuropeptide Y, OEF = Operation Enduring Freedom, OIF = Operation Iraqi Freedom, PTSD = posttraumatic stress disorder, RIA = radioimmunoassay, TC = trauma-exposed healthy control, VA = Department of Veterans Affairs, V[O.sub.2] = oxygen consumption.
Pharmacodynamic parameters such as heart rate, augmentation pressure, augmentation index (Alx), subendocardial viability ratio (SEVR), radial and aortic blood pressure (BP) were recorded before and after the cold pressor test
at baseline and at the end of treatment.

The data presentations at AAPM show that NKTR-181 produced a clear dose-dependent analgesic response in a cold pressor test
, a model of pain used in healthy subjects to measure CNS analgesic activity.
In the measurement, a five minutes cold pressor test
was executed in each subject and also each subject done exercise using a bicycle ergometer in five minutes and walked during 15 minutes.
However, the cold pressor test
, performed by placing the patient's left arm in ice-cold water, resulted in 30-40% narrowing of the Cx artery (Fig.
Asymptomatic volunteers scoring highly on the PCS (> 24) report significantly higher pain during the cold pressor test
and painful medical procedures than patients with lower scores (Sullivan et al 1995).
(27) While it has been suggested that young blacks have higher resting HRV, they have also been shown to have higher HRV in response to isometric handgrip, cold pressor test
, and the valsalva maneuver.
